Default RE: Yet another Sig Something Extra Build

I have a couple of planes that when they stall they just drop the nose. Granted they are high wing trainer types, with constant cord wings, they are not high aspect type of wings, and they are light wing loading.

I have read that, with high aspect wings, flaps will significantly reduce the chance of of a tip stall. According to what I have read flaps raise the AOA at the wing root so that it stalls before the wingtips will, reducing the chance of snap. Most of my older warbird aircraft and some of the scale ones, are in the 30 oz wing load range, and do indeed fly like a brick, and you want to talk about snapping when you don't want them to.

I want this plane to be able to be fly as well as it was designed to, despite the fact that I have a whole myriad of changes I intend to make. I want to be able to adapt the plane for a number of purposes, or payloads but still perform as well as originally designed, if not better, with a bit larger flight envelope. Adding the weight of the cowl, cooling vent, wing fairings, sheathing, and structural upgrades to the fuselage and tail feathers; will be difficult to do not adversely affect the performance because of the added weight.

I intend to post the build and keep it updated until at least the maiden flights, and test have been performed.
